Personally I find both of them flawed at the same point, namely thinking that measuring/recording with a specific rig or real ear will give results that can be generalised, unfortunately the variation of human HRTF tells the contrary so I am afraid there will never be absolute judgements, scores and EQs for headphones.
Well contradiction is that we are listening to Oluv's video through different headphones. What I do like that is that he switches from headphone to headphone, his review of a headphone isn't just that headphone usually. So you can at least somewhat hear the difference between the headphones.
Sean can say whatever nonsense he wants, he's just a shill for Harman. This thread focuses too much on Oluv's measuring and recording methods, when that's not what his channel is about. His channel is about listening to music, the gear is the tool for that. His methods point out the obvious flaws and often uses EQ to rectify that. Finding reviews for headphones IMO is really trying to find a reviewer who has similar sound preference, Oluv and I seem to be alike, I like him. Bad Guy Good Audio Reviews I sorta appreciate his angle on how he reviews gear, but he and I don't hear alike and his choice in music is also different. He praises gear that makes his favorites sound great and I'm not a fan of them, so it makes sense. I can appreciate that, from a guy who doesn't care all that much about graphs and has open disdain for Harman, which I also like.
I think reviewers should be like Oluv and Bad Guy Good Audio Review, they should grow some balls and review headphones based on their preferences and what they like and not conforming to ideals from any group of people or some frequency graph. Once the viewer or reader can assess what kind of sound they like, their reviews become valuable.
This was the same with Tyll, once you know what flavor of sound he likes his reviews make more sense. And I can appreciate Tyll for standing by his style of reviewing.
Also at least I get the sense Oluv listens to music. Sean Olive likes to listen to graphs from random 200+ people's preferences.
I enjoy his vids cause he's clearly having fun with audio. He doesn't come off like a douche like The Headphone Show guy does. His wireless bluetooth speaker vids are his best vids.
The thing that disturbs me most with Oluv isn't Oluv, it's that he's had TWO Elex headphones break and his friend also has dead Elex, 3/3 Focal Elex dead headphones. That's truly disturbing.
